I mainly use neovim and I found that setting :set textwidth=0 in ${HOME}/.config/nvim/init.vim has no effect.Textwidth is always 78.
The reason is that other scripts overwrite my settings, I found textwidth=78 in other scripts:
$ sudo find ! -path "./home/**" -name "*.vim" ! -path "./proc" ! -path "./run/**" ! -path "./root/**" | xargs grep "textwidth=78"
./usr/share/nvim/runtime/syntax/ada.vim:"vim: textwidth=78 nowrap tabstop=8 shiftwidth=3 softtabstop=3 noexpandtab
./usr/share/nvim/runtime/indent/ada.vim:" vim: textwidth=78 wrap tabstop=8 shiftwidth=3 softtabstop=3 noexpandtab
./usr/share/nvim/runtime/ftplugin/changelog.vim: setlocal textwidth=78
./usr/share/nvim/runtime/ftplugin/help.vim:setlocal formatoptions+=tcroql textwidth=78
./usr/share/nvim/runtime/ftplugin/javascript.vim:" vim: textwidth=78 tabstop=8 shiftwidth=4 softtabstop=4 expandtab
./usr/share/nvim/runtime/ftplugin/ada.vim:" vim: textwidth=78 nowrap tabstop=8 shiftwidth=3 softtabstop=3 noexpandtab
./usr/share/nvim/runtime/ftplugin/occam.vim:setlocal textwidth=78
./usr/share/nvim/runtime/compiler/decada.vim:" vim: textwidth=78 wrap tabstop=8 shiftwidth=3 softtabstop=3 noexpandtab
./usr/share/nvim/runtime/autoload/adacomplete.vim:" vim: textwidth=78 wrap tabstop=8 shiftwidth=3 softtabstop=3 noexpandtab
./usr/share/nvim/runtime/autoload/decada.vim:" vim: textwidth=78 wrap tabstop=8 shiftwidth=3 softtabstop=3 noexpandtab
./usr/share/nvim/runtime/autoload/ada.vim:" vim: textwidth=78 wrap tabstop=8 shiftwidth=3 softtabstop=3 noexpandtab
The number of these scripts is a bit large, I don't want to delete them one by one, and I want to avoid modifying scripts that I don't understand as much as possible.
How should I force automatic line breaking off?
You should take a look at :help fo-table as it's actually your :h 'formatoptions that is responsible to wrap the lines when typing in insert mode, see the t letter.
You can remove the letter with:
set formatoptions-=t
You can identify where an option is set with the :h :verbose command:
:verbose set tw?

I recently upgraded to fish 3.0.1 via Homebrew 2.0.1 on MacOS Mojave 10.14.2. Since the upgrade, the following error message appears every time fish starts:

What's going on here? How can I fix this?
What happens here is that a component of your $PATH, $fish_user_paths or a line in /etc/paths looks like an option.
Most likely, this is wrong, and you should remove it.
E.g. try printf '%s\n' $fish_user_paths. If that tells you that one of the entries is "-gx", then you've set it incorrectly and need to use set -e fish_user_paths[number-of-that-entry] to correct it.
Since these are all common options to set, you've probably once done something like set fish_user_paths /something -gx, which adds a "-gx" component (set only reads options before the variable name).
This has been reported upstream at https://github.com/fish-shell/fish-shell/issues/5662, and future fish versions won't spew an error, but the existence of the offending component is most likely an error, so you still want to remove it.
I love Fish shows me "git status" in the prompt. However, it doesn't work well for really large git repos because it's very slow. How can I disable this feature based on the directory's name? Thanks!
Here's what I did. You need to replace those <REPO>
function fish_prompt
set last_status $status
set_color $fish_color_cwd
printf '%s ' (prompt_pwd)
set_color normal
set BIG_REPOS <REPO1> <REPO2> <REPO3>
if not contains (basename $PWD) $BIG_REPOS
printf '%s ' (__fish_git_prompt)
end
set_color normal
end
I'm trying to get my config.fish to work, but it's not working as expected, and I really can't understand why. The best I can do is guess that maybe Fish can't handle if statements within if statements? Here's my code:
echo "so far so good"
if status --is-interactive
# Chips: fish plugin manager
if [ -e ~/.config/chips/build.fish ] ; . ~/.config/chips/build.fish ; end
echo "def interactive"
# Don't use vi keybindings in unknown terminals,
# since weird things can happen.
set acceptable_terms xterm-256color screen-256color xterm-termite
echo "acceptable terms: $acceptable_terms"
echo "term: $TERM"
if contains $TERM acceptable_terms
echo "good to go!"
fish_vi_key_bindings
# Load pywal colors
cat ~/.cache/wal/sequences
else
echo "why?!?!?"
end
end
And what I'm getting is this:
so far so good
def interactive
acceptable terms: xterm-256color screen-256color xterm-termite
term: xterm-termite
why?!?!?
But what I expect to see is this:
so far so good
def interactive
acceptable terms: xterm-256color screen-256color xterm-termite
term: xterm-termite
good to go!
But when I run this in a shell, if works fine:
❯ echo "term: $TERM / acceptable: $acceptable_terms"
term: xterm-termite / acceptable: xterm-256color screen-256color xterm-termite
❯ if contains $TERM $acceptable_terms
echo "yay!"
end
yay!
What could be going on here?
Of course fish can handle nested if statements!
if contains $TERM acceptable_terms
is missing the $ on the second variable!
if contains $TERM $acceptable_terms
I would like to change variables within NSIS through command line arguments. I see in the documentation you can change global variables, but not created ones within the NSIS script.
For example: if I had
Var example
StrCpy $example "C:\Program Files (x86)\Installer"
Is it possible to change the example variable string through command line arguments?
OutFile "MySetup.exe"
Name "MySetup"
RequestExecutionLevel user
!include FileFunc.nsh
!include LogicLib.nsh
Var MyVar
Function .onInit
StrCpy $MyVar "Default value"
${GetParameters} $0
ClearErrors
${GetOptions} $0 "/MyVar=" $1 ; Get suffix after "/MyVar=" switch
${IfNot} ${Errors}
StrCpy $MyVar $1
${EndIf}
FunctionEnd
Section
MessageBox mb_OK MyVar:$MyVar
SectionEnd
and execute as "MySetup.exe" /MyVar="Hello world"
I've installed perlbrew and it works: when I do a 'perl -v' in a terminal, it reports that I'm using perl 5.14. But gvim (vim instead works) still thinks that I'm using 5.10...
How do I set the perl path for gvim?
thanks
You can set the PATH variable in .vimrc:
let $PATH = "~/bin:" . $PATH
You can take a look at what it is by
:echo $PATH
There's also trick to enable path defined by perlbrew, so you don't need to change your .vimrc once you switched to other perl version:
" Enable perlbrew path
if has("gui_running") && filereadable($HOME . "/perl5/perlbrew/etc/bashrc")
let $PATH=system("source " . $HOME . "/perl5/perlbrew/etc/bashrc; echo -n $PATH")
endif
Put this code in your .vimrc and restart vim
